Try a factory reset. Make sure that you backup any important data before performing factory reset.
FYI, this is an Xperia V thread, not Neo.
Anyway...
If you already tried a factory reset, then you may need to recover the firmware to a well known state.
But first do a backup (repair will erase your phone)!!
Here's some guidance on that:

Then, repair your phone with:

Also, be sure to jump to the Neo V thread.
